High-Power Coherent Emission From Arrays of Resonant-Tunneling-Diode (RTD) Oscillators

In this contribution, we will present the high-power coherent terahertz (THz) emission from resonant-tunneling -diode (RTD) oscillator arrays. The RTD oscillators possess the highest oscillation frequency among all electronic THz emitters [1]. However, the emitted power from RTD oscillators remains limited [2], [3]. To address this issue, here, we propose and demonstrate two RTD oscillator arrays to achieve high power coherent THz emission: a linear array and a two-dimensional array.
